Fish Sense

The critical decline in freshwater species presents a significant challenge with widespread impacts on ecological balance, livelihoods, and food security. According to a report by Aliza Chasan on CBS News dated December 11, 2023, thousands of freshwater species globally face extinction, with 25% of them at risk. Climate change is worsening this issue, affecting at least 17% of threatened species through factors such as rising sea levels, pollution, invasive species, dams, and water extraction.

Uganda has 293 fish species, 40 (13.3%) of species are threatened with extinction. This decline has resulted in a national fish supply deficit of over 588,706.3 tonnes, affecting more than 5.3 million people who rely on fish for sustenance. In response, authorities in Uganda have displaced over 10,000 fishermen on Lake Victoria alone, accusing them of catching undersized fish. Illegal fishing methods persist, leading to an annual economic loss of US $429.6 million. Moreover, large commercial fish stocks in Lake Victoria have declined from 1.3 million tonnes in 1999 to 300,000 tonnes in 2008, representing a significant loss in value of US $1.9 billion and a 75% decrease in fisher income.

This displacement emphasizes the urgent need for conservation efforts and alternative approaches to meet the rising demand for fish, as 85% of Ugandan households consume fish. Transitioning to controlled fish farming is considered a viable alternative solution for displaced fishermen and a means to promote aquaculture for increased fish production. However, the 12,000 existing aquaculture farmers in Uganda face significant economic losses of 30–40% due to poor feeding and management practices. These losses encompass operational costs, feed wastage, fish stock losses, water pollution, market losses, inadequate feeding frequency, insufficient feed consumption monitoring leading to growth issues due to under/overfeeding, and inadequate water quality management.

Addressing these challenges requires a diverse approach that focuses on improving feeding and management practices in aquaculture. Implementing solutions to enhance feeding frequency, optimize feed consumption monitoring, and improve water quality management can mitigate economic losses and ensure the sustainability of fish farming operations. This approach is crucial not only for the livelihoods of thousands of farmers in Uganda but also for global efforts to conserve freshwater species and secure food security for millions of people worldwide.

Fish Sense is an automated solar fish feeder that employs AI for accurate feeding while integrating water quality control, wastewater recycling, and mobile monitoring. It incorporates cutting-edge components, including networked sensors for real-time water quality detection and optimization, radiator devices to address changing water quality conditions, a wastewater recycling mechanism, AI-driven precision feeding and analysis swimming pattern, real-time mobile monitoring, and data-driven insights to ensure optimal performance.

The utilization of artificial intelligence, along with features like reports and an information chatroom, not only enhances fish farming efficiency but also represents a sophisticated application of technology in aquaculture. Furthermore, the tool's ability to tackle the complex challenge of deteriorating water quality through innovative networked sensors, precise feeding to prevent water contamination with uneaten feeds, and wastewater recycling showcases a high level of scientific sophistication.

By seamlessly integrating these advanced technological elements, our solution, "Fish Sense," redefines aquaculture practices, promoting environmental sustainability, food security, and economic viability in a region wrestling with complex ecological and livelihood issues.

Fish Sense, our solution, is tailored to restore fish species for ecological balance but also benefit fish farmers, particularly in lakeside and riverside villages where traditional aquaculture practices fall short in meeting the growing demand for fish caused by environmental concerns. This innovation significantly impacts the lives and livelihoods of these fish farmers by enhancing their commercial fish production capacities, improving feeding efficiency, and implementing effective operation monitoring strategies. The current challenges they encounter, including declining freshwater fish supplies to the market, limited access to wetlands, manual poor feeding management practices, and water quality degradation, are effectively addressed by Fish Sense.

Our solution introduces a comprehensive and innovative approach, featuring AI-driven precision feeding and swimming pattern analysis, real-time water quality monitoring, and wastewater recycling mechanisms to elevate fish farming efficiency. The target population, often neglected by conventional methods, gains substantial benefits from Fish Sense, optimizing feeding practices, preventing water contamination, and promoting sustainable aquaculture. By elevating the overall efficiency and environmental sustainability of fish farming, Fish Sense plays a crucial role in supporting the livelihoods of fish farmers. It ensures economic viability, food security, and a more environmentally friendly approach to aquaculture, particularly in the Lake Victoria regions and other areas confronting complex challenges

Our team is passionate about aquaculture farming, our team lead cultivated fish in tanks from a young age, recording failures. He pursued the same project line for his master's research, aiming to understand and find solutions to improve controlled fish farming with advanced technologies. This Our technical director is passionate at utilizing artificial intelligence to automate solutions, together as a team reinforcing our close connection and understanding of the communities we aim to serve. We prioritize a hands-on, community-centric approach that extends beyond academic or professional credentials.

The team lead's home village, located in lakeside villages, specifically Lake Victoria in a village named "Katosi," has direct ties to the community. Here, the team lead interacted with fishermen and witnessed the displacement of fishermen by authorities due to poor fishing practices. This shared background mirrors that of the target population, allowing us to intimately comprehend the challenges faced by fish farmers in these communities. Our firsthand experience with the local context ensures that our solution is not only technically sound but also culturally and socially relevant.

The design and implementation of Fish Sense are meaningfully guided by the input, ideas, and agendas of the communities we serve. We actively engage with community members through workshops, focus groups, and ongoing dialogue to understand their unique needs, concerns, and aspirations. This collaborative approach ensures that our solution aligns with the practical realities and preferences of the fish farmers. Regular feedback loops and community involvement are integral parts of our development process, ensuring that Fish Sense is a solution tailored to the specific requirements and details of the target population
